GP300S / GP330 European Style Single-Cylinder Hydraulic Cone Crusher for High-Inertia Heavy Crushing

The primary difference lies in the intake capability and structural focus. The GP330 features a much larger feed opening (up to 370 mm), allowing it to act as a heavy secondary crusher receiving larger chunks directly from a primary jaw crusher. The standard GP300 has a tighter feed intake and is more commonly optimized for tertiary fine crushing or standard secondary configurations.

The intelligent IC control module continuously monitors real-time parameters such as hydraulic cylinder pressure and motor load. As the manganese liners naturally wear down over time, the system automatically lifts the main hydraulic piston slightly to maintain your exact target Closed Side Setting (CSS), keeping product distribution uniform without manual calibration gaps.

The GP330 features an adjustable eccentric sleeve that allows site engineers to modify the stroke length. This provides the flexibility to optimize the crusher to changing site conditions. For example, you can select a longer stroke for maximum output during secondary crushing, or a shorter stroke for higher rotation speeds during fine tertiary loops to maximize product shape.

We standardize on premium high-manganese steel mixed with Chromium, specifically Mn18Cr2, for all our GP330 aftermarket wear components. This advanced metallurgical formula creates an ideal balance of fast surface work-hardening under high crushing impacts while maintaining a ductile inner core to prevent brittle fracturing.

When an uncrushable object (such as a steel loader tooth or rod chunk) enters the chamber, the hydraulic system experiences an immediate pressure spike. The smart bottom-mounted cylinder reacts instantly by opening an accumulator valve, allowing the main shaft to drop and pass the tramp iron safely. The system then automatically restores the shaft back to its original setting.

The net base machine weight of the GP330 is approximately 19,800 kg. Thanks to its compact vertical profile and lack of bulky external spring arrays or clamping rings, it fits comfortably into a standard 20-foot GP ocean container, keeping international freight logistics simple and cost-effective.

We support the GP330 European Style Cone Crusher with a full 12-month structural warranty, covering the main cast housing frame, main shaft assembly, countershaft, and bevel gear sets against any material or manufacturing defects. Regular high-wear castings like mantles and concaves are excluded but are heavily stocked for rapid global delivery.
